<p>[QUOTE=&quot;-jeffB, post: 3563611, member: 27832&quot;]Yeah, and the problem is this: you&#039;re not just conducting heat from the air to the ice, you&#039;re cooling down your piece of metal. In fact, I expect <i>any</i> melting you measure comes from cooling the metal down to the temperature of the ice. (Try it with silver and copper coins that are already cooled down to 0, and see if you can measure a difference!)</p><p><br /></p><p>Silver has <i>slightly</i> better thermal conductivity (~5%) than copper, but copper has higher <i>specific heat</i>, which means it&#039;ll absorb more energy while you&#039;re cooling it down. I&#039;d need to run controlled experiments, but I wonder if copper wouldn&#039;t actually melt the ice <i>more quickly</i> than silver.</p><p><br /></p><p>(Edited to fix direction of heat transfer <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie10" alt=":oops:" unselectable="on" unselectable="on" />, thanks [USER=102913]@Tlberg[/USER]...)[/QUOTE]</p><p><br /></p>
